I SPECIFICATION forming; part of Letters Patent No. 744,991, dated November 24, 1903.

Application filed october 2 1, 1902. Serial No- 128,546. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOSEPH O. ACHTERMAN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Cans, of which the following is a specification.

My invention relates to improvements in metal cans, barrels, and other vessels, the object of the invention being to reinforce, protect, and strengthen the cylinder or body of the Vessel by strengthening bars, ribs, or hoops constructed as shown in the drawings and as hereinafter described and claimed.

In the accompanying drawings, to which reference is made and which form a part of this specification, Figure 1 is a front elevation of a can or barrel made in accordance with myinvention, the strengthening-bars being applied vertically. Fig. 2' is a sectional plan view of the same. Fig.3 is a front elevation of a can or. barrel having the strengthening-strips applied around the body or cylinder, and Fig. 4 is a detailed perspective View showing the construction of one of the strengthening ribs, bars, or hoops.

In the drawings, 2 designates the body or cylinder of the can or barrel provided with a bottom 3. Upon the said body or cylinder are secured by rivets or otherwise strengthenin g bars or ribs 4, as many as desired. These bars or ribs are hollow and formed with a flange 5at the sides by which they are fastened to the body of the can or barrel. They are by preference V-shaped, as shown, and are by preference rolled or formed up in a die from sheet metal. Inside of some or all of said hollow bars or ribs is placed a strut or brace 6, which takes its base against the body or cylinder of the can or barrel and supports the hollow bar or rib, as shown in Fig. 2. Each strut or brace 6 is by preference in the form of a T, having base-flanges 7 at each side, and they are by preference rolled or formed up in a die out of sheet metal, as shown in Fig. 4that is to say, astrip of metal is folded on itself to form the brace 6, the edges being bent outward to form the flanges 7; but I do not limit myself to the specific form of strut or brace, as T-iron or other forms of brace may be used.

In Fig. 3 the body or cylinder 2 has the strengthening strips applied horizontally around the same instead of vertically, as shown in Fig. 1. In this form the strengthening-bars at and struts 6 are the same in construction as in Figs. 1, 2, and 4, except they are in hoop form.

In making the can or barrel lprefcr to make the body or cylinder of sheet-iron or sheetsteel. The strengthening-bars and struts are then applied, and then the whole is in most cases galvanized by immersion in a bath of zinc or tin, which not only coats the outer surfaces of the body, but also coats the interior of the strengthening ribs or bars and secures the struts or braces firmly in place. When used in hoop form, the strut is put upon the body first oris placed in the strengthening-bar and then both applied together to the body or cylinder, whether galvanized or not. By this construction the. strengtheningribs each have a wide base upon'the body or cylinder of the can or barrel, and the struts also each have an intermediate base against or upon the body of the can or barrel within the strengthening-strips, and the strengthening-strips hold the struts from lateral displacement, so that a double thickness of material and a double base are provided to sustain any blow, jam, or crushing strain that would otherwise come upon the body of the can or barrel.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. A vessel the body of which is provided with hollow strengthening-ribs made separate, and having marginal flanges by which they are secured to the outside of the vessel, in

combination with other strengthening-ribsmade separate and inclosed in the first-named ribs, and each formed with marginal basefianges which rest against the body of the Vessel, and with a central flange at right angles with said marginal base-flanges, and which latter supports the apex of the said inclosing rib, substantially as described.

2. A vessel the body of which is provided with hollow V- shaped strengthening ribs made separate and having marginal flanges by which they are secured to the outside of the vessel,in combination with other strengthing the apex of theinclosing rib, substantially ening-ribs made separate and'inclosed in the as described. first-named ribs, and each formed with marginal base flanges which rest against the 5 body of the vessel, and with a double central Witnesses:

flangeat right angles to the said marginal JOHN W. WALLACE, base-flanges, the said double flange support- 0. H. BAINBRIDGE.
